Researchers introduce TIED (Transformation-Inverting Energy Diffusion), a novel machine learning method that recovers inverse transformations on Lie groups using diffusion sampling. The approach improves neural network robustness to input transformations at test time, with applications in image processing and physics-informed modeling.
Researchers propose Lie Group Embedded Dynamical Neural Networks (LieEDNN), a novel neural architecture that leverages Lie group mathematics to model continuous symmetries in dynamic systems. The approach enables stable, learnable dynamics on smooth manifolds for applications in robotics, graphics, and control systems, with experimental validation on SE(3) group structures for telescopic manipulator control.
Researchers propose VPSD-RL, a reinforcement learning framework that discovers value-preserving structures in continuous control tasks using Lie-group operators and diffusion models. The method improves data efficiency and robustness by identifying nonlinear transformations that preserve optimal value functions, addressing brittleness in RL systems under environmental variability.
Researchers introduce LieFlow, a machine learning framework that automatically discovers symmetries in data by treating symmetry discovery as a distribution learning problem on Lie groups. The approach can identify both continuous and discrete symmetries within a unified framework, significantly outperforming existing methods like LieGAN in experiments on synthetic and real datasets.
